uniform server as service - not using configured mysql port

I've installed Uniform server successfully and can run the Server as a standalone program. For MySQL I've chosen a non-default port (3386), by changing it using the controller. And it works great - Unless I install the Uniform Server as a Service (using UniService.exe). It appears that MySQL now listens on the default port 3306 and not on the one that I've configured before. (For apache I've chosen a non-default port as well (85) but no problems here) Anyone experienced this behaviour? Your help woul be appreciated.
